HEATING-STOVE.

`The Schedule referred'to in these Letters Patent and making pax-t of the same.

To all whom it may conce-rn:

Figure 1 represents a perspective view of' the hea-` ter or stove as improved, with parts of the ontei and inner cylinders broken away', showing improvements. Figure 2 is a vertical lateral section through dotted line No. l, in fig. 4.

Figure 3 is the same through dotted lines No. 2, in fig. v4. Figure 4 is a vertical view through line No. 1, in

Figure 5 is a cross-section, on' an enlarged scale,'

through fire-pot and perforated air chamber.

Figure 6 is a vertical view of the grate and its adjuncts, on an enlarged scale.

Heaters and stoves for warming several rooms in a building do not, as a general rule, furnish the amount of warm or hot air they should to such rooms for the amount of fuel consumed on account of- First, imperfect combustion of the fuel used, much of which passes off and escapes in the form of' uiiconsunied gas oi smoke.

Second, on account of' the loss of heat by radiation in the heater or stove-room.

Third, on account of the heated aii'not being retained a longer time in contact with the several heating partsof the apparatus.

Fourth, on account. ot' the .difficulty of removing the clinkers that accumulate near the bottom of the tire-pot above the grate.

To ena-ble others to understand my invention I will describe it iu reference to the drawing and the letters of reference marked thereon7 the same letters indicating like or similar parts.

[n the drawing- A represents the base of a stove or hea-ter.

15 is the lower circular air-chamber, communicating with the open base below by the peiforations ad, figs. 2 and 3, and to the chamber above by the perforation b, figs. 1, 2, and 3. p

Grepresents the fire-box lined with fire-brick D, figs. 2, 3, and 5.

Placed immediately over the fire-pot C is au airheating chamber, E, hung by a projecting flange, e,

-tigs. 2, 3, and 5, the edges of which fiange e rest upon the top edge of the tire-pot C.

lhe said-airheating chamber E depends down with sloping sides c to, and terminates at, its bottori i,wliich bottom continues but a short distance, aiid meets the inner sides c' o f the said chamber, which sides c' rise np conc-like, and terminate in a fine, c,'or pipe..

with a small opening, shown in figs. 1, 2, 3, and 5.

rIhe sides o arid o' of the chamber E are furnished with perforations .t z, through which perforations z the air (entering the said chamber E) passes out to impinge in all directions on the gas and flame as they may ascend in the fire-pot, upward, at the sides and in the center of the same, as they (the gas and fianie) may be drawn by the draught through the fines we, and the central fine c". The top of the chamber E is formed by the plate S, aud is furnished with draught-holes :c figs. 1, 2, 3, and 5, which are placed directly over similar draughtlioles made iu the ilange e; a damper, S,vis interposed between the said top-piece S of the chamber E, and the snpporting-fiange c of' the piece forming the chamber E, which damper may be closed or opened at pleasure by means of the projecting stem x', fig. 1.

The fire-pot C is surrounded by a cylinder or jacket., F, figs. 1, 2, 3, and 4, forming a heating-chamber, F', which chamber Fis divided by the rim figs. 1, 2, and 3, starting out from the top of the fire-pot C, and fitting to the inside of the cylinder. F, thus forniiiiga second or lower chamber, F", within the said cylinder F, and below the chamber F; a communication is made with the upper chamber F to the chamber F i below, by means ofthe opening y, figs. 2 and 4, made in the projecting rim j".

In the top of the upperA chamber F is made a flue, in, which tine is provided with a damper, m', figs. 2 and 3, operated by a handle or rod shown in fic. 1.

The heater is also provided with a second' outer jacket or cylinder, G, which iiieloses all the parts of' the heating apparatus.

This outer jacket vmay be lined with fire-brick, soap-stone, or any other suitable,non-conducting niaterial, g, figs. 1, 2, and 3. 'lhe top of the said louter jacket riiay also be lincd with non-conducting material the same as the inside of the said jacket.

Leading from the top of the outer jacket are fines, one or more of which communicate with the room or roomsto be heated.

The chamber formed by the said jacket G is divided by the projecting rim of' the top of the inner jacket F, forming the upper chamber G, and lower chamber Gr", and communication is had fioin the said lower chamber G" to the upper chamber G by means of the openings u n, fic. 1.

'lhe air to be heated in the chamber (ir and G is admittedto the same through the openings 71,' figs. 1 and 2, made in the base.

I also run through the inner chamber F', above the fire-pot G, a tine, H, (or several of'tliem, crossing cach other over one another,) which flue H draws air through the perpendicular' -pipe H' from the base B, fig. 3, and discharges the air thus drawn, when heated, throughthe exit-pipe When several such pipes H are passed through the said chamber l1", cach drawing from its feed-pipe H', and discharging through their exit-pipes H", I would place them one above the other crosswise, and would lead from the pipe nearest to the fire-pot into the coldest room in the building to be heated; and the pipe next above I would lead to the next coldest, and so on, and, in so doing, I would be able to use and discharge in several different rooms each a different tem? perature of heat.

'lo supply air to the air-heating chamber E, gs. 2, 3, and 5, (to be heated and impinge on the flame, gas, and smoke,) I form outside the fire-pot C achamber, O, figs. 1, 3, and 4, and I connect the said chamber O with the hot-air chamber E by means of the pipe O leading into the lower part of the said chamber o in a feed-pipe p, which draws from the pipe p'.

The said pipe p connects with a pipe, p, into which it can be moved vertically upward sufficiently touncover the opening of the pipe P.

The pipe p is intended to lead from a n air-tight chamber or other room in theupper part of the building, and draw therefrom the impure air that is apt to rise from below.

' When the pipe p is thrown up vertically so as to uncover the opening of the pipe p, the air fed into the air-chamber E will be drawn from the heater-room.

I also make, in the stove or heater, on a plane with the grate J, an opening or flue, lr, which opening is covered by the incasing piece R, fig. 2 the said incasing piece is constructed with sides It R', fig. 4, which project down from the top R, and rest on the base-plate below, as shown in lig. 2.

Being thus constructed, the said incasing piece R cuts otf all communication of the said opening or flue r with the chambers 14" and G at that point, and renders the said opening r the same as a flue to conduct air into the fire-pot C in a horizontal line of direction with the top of the grate.

I also lead from the bottom of the chamber o a flue, o", figs. l and 4, which flue o communicates with the covered opening or flue r; at the point of juncture of the flue r wit-l1 the flue 0".I make a damper, r', by which damper the air can be cut ot` fromentering the said ue fr from the flue oleading from the bottom of the chamber o, fig. 4, or the air can be permitted to enter the said flue fr to feed the fire on a horizontal plane with the top of the grate.

By means of the several fines, (the fjue o leading into the chamber E from the chamber o, and the flue o" leadingr from the same said chamber o to the flue or covered opening r, when 'the damper r is Aset to open the same,) air drawn by the pipes p p p into the chamber o will feed into the chamber E above the fire, andthrough the flue r into the base of the fire-pot 011 4a horizontal plane with the top ot the grate J, at one and the same time.

The opening r extends from the outer cylinder of the heater into the fire-pot, and is provided inl its floor with a dump-hole, t, through which clinkers (when drawn out from the fire-pot) may be passed to the ash-pit 'u below.

This opening r serves theA double purpose of feed'- ing/air into the fire-pot at its base, from the chamber o, andalso of affording means for the removal of the cinders and clinkers that are apt to accumulate above the grate, and cannot be made to pass through the usual openings in the grate, which clinkers can, through this opening r, be removed by means of a poker, or other suitable instrument.

The grate J, made in any suitable manner, is hung at its, rear by a jointed rollerbar, q, fig. 2, and in front by the lever handle q.

firmly heldin a horizontal position for the mass of fuel to be supported, and can be readily and freely vibrated when desired, and easily dumped by the rolling of the jointed roller-bar q and the lever-handle q in their places or bearings.

'lo operate with this heater orstove, the fuel placed in the usual fire-pot G, through the feed-mouth W, figs. 1 and 2, and the fire lighted; the damper S', fig. 5, is then turned open, and also the damper/in in pipe M, fig. 2, when the draught will be direct.

W'hen the fuel has become wellignited, the damper 'm' may be closed, andwhen closed the products of combustion will pass into the chamber 11", thence down into chamber F", thence into the chamber through the several openings or ports provided, as

"shown by arrows in fig. 2, thence up and out through the fines or pipes K and M.

When the damper S', fig. 5,-is closed', the air dra'wn from pipes P, P', and P7 or from P alone, will pass into the chamber o, and from thence through the fine o into the chamber E, figs. 3 and 5, in the manner indicated by arrows, and, after becoming heated, will pass out through the perforatiens zz into the firepot C, to act upon the gas and flame in several direc- 4 '5 tions.

When the damper Ir', at the junction ofthe flue o, with the fine r, is opened, a portion of the air drawn by the pipes P P P will be admitted from the chamber o into the said flue or opening r to feed the fire at the base of the fire-pot C, and above the grate J, and ou a plane with the top of the same; while the other portion of the air drawn by the said pipes P P P will feed into the chamber E above the fire, and, when the damper r is closed, (and the hole in the base of the fire-pot facing the flue r is uustopped,) the air will be fed into the face of the fire-pot above the grate, provided the outer door of the said flue or covered opening fr is opened.

When air is admitted into the pipe H' from any suitable opening either in the base of the stove, as shown in fig. 3, or elsewhere, the said air will pass into the air-pipe H, running horizontally over the fire-peti), and become heated to a high degree of temperature, and is led ofi' through the pipe H" to the room or rooms to be warmed. Several such horilzontal pipes H, crossing one another, and placed one above another, can be .used to good advantage to warm rooms remote in a building.

The air to be heated in the outer chambers G and G" formed between the inner jacket F and outer jacket G, finds entra-nce into the said chambers from the base below through the parts provided,l as shown, and passes in the manner indicated by dotted arrows to the usual distributing-pipes to be conveyed to the several rooms to be warmed.
